What about those who know he's a lying sack of shite yet support him because he serves their interests, namely greed and grift?

What about those who are far from stupid but have enabled, encouraged, and empowered him because he ensured unchecked greed and grift would continue apace?

Those are educated, wealthy, and influential people who were only too happy to line their pockets for 4 years.

Dumbasses don't know better than "As Seen on TV" and are easy to manipulate...

This whole presidency was a massive scam that spawned many more, alas.
